PROCESS OF TREATING REFUSE.

Specification of Letters Patent.

Patented Apr, 23, third.

To all whom it may concern:

Be it known that l, l-llnrnnrcrr G, Bren- MANN, a subject of the GermanEmperor, re siding at Perth Amboy, in the county of Union and State ofNew Jersey, have'invented certain new and useful Improvements inProcesses of Treating Refuse, of which the following is a specification.

The present invention relates to refuse destroyers and has for itsobject to provide a method of edectively treating refuse, includingincineration of the same.

it have found that in refuse destructors of the hitherto knownstructure, the fine constituents of the refuse, such as fine ashes,street sweepings, etc., always render more or less difficult thedestruction of the combustible matter, with which they are generallymixed. This fine incombustible matter also materially decreases thecapacity of incinerators, if, either mixed with the general refuse, orseparated it is charged into the same combustion chamber of theincinerator, It also materially increases the cost of incineration ifthe fine matter is separated from the coarse refuse and both are burnedin separate and differently constructed furnaces.

The hereinafter described process entirely obviates the above mentioneddisadvantages and consists in that the refuse is first sepa rated andthe fine constituents of the refuse are charged into any part of theincinerator, which is passed by thehot waste gases coming from theincinerating chamber, instead of charging the refuse into theincinerating chamber, while'the coarser constituents are dum ed into thelatter; The part into which the fine parts of the refuse are charg d maybe situated anywhere between the incinerating chamber and the chimney.

To carry out my process it provide anap paratus which is illustrated inthe accompanying drawing.

y in the drawing the figure is. a sectional diagrammatic view of theapparatus, similar reference characters therein denoting correspondingparts.

1 designates the discharging floor, 2 the stoking or clinlrcring floorand 3 the charging floor or top of the incinerator. The incinerator isprovided with an opening a, and

a funnel 5 ileading into a perforated rotary drum 6 arranged in aninwardly inclined position and opening into the incineratlng chamber'2', 8 denotes the dust chber which by a partition 9 is divided into twosuperposed compartments of which the upper one contains the drum 6. Thetwo compartments are connected by a passage 10 made in the partition 9and which is large enough to allow the passage of fine refuse from theupper compartment into the lower one and to allow the heat from thelower compartment to enter the upper compartment. Above the drum 6 theincinerator is provided with manholes 11 through which theperforations-of the drum can be cleaned, if necessary. I

Of course, instead of a rotary drum, any other suitable refuse feedingand sifting means may be employed. 12 denotes a fireclay platform, onwhich the refuse coming from the drum will rest and on which it willstill morehighly be heated by the radiating heat of the dust chamber 8and of the smoke fine 13 as well as by the waste heat producedby theincineration taking place on grate 14. 15 denotes the clinker chamberprovided with sniall air holes 16. Characters 1'? denote working doorsand 19 valves leading into the discharge chambers in which cars 20running on tracks are provided. 21 is a gas flue connecting the dust andincineratmg chambers and .22 is a flue connecting the dust chamber withthe smoke due 13, which also is provided with means for removing theresidue of flue dust and from which the gases pass to theboilers or thechimney.

Myprocess is carried out in the following manner:

if there is only a small percentage of fine material in the refuse, thelatter may be dumped directl into the incinerator through the opening 4:t rough which also large bed ies, such as dead animals, bones,mattresses,

etcq'vmay' be inserted. lf the refuse is mixed with large masses ofashes, sand, etc, it may be dumped into the funnel 5 leadihg into thedrum 6. The rotation of the drum and its inclined osition will cause thecoarse articles or bodiestof refuse to gradually rop into theincinerating chamber '2', while the fine particles will be siftedthrough the per forations of the drum into the dust chamber 8 Theartition '9' will rotect the steel drum 6 "'rom the intense seatreigning in the lower compartment of the chamber 8,

while the opening 10 will permit the fine particles of refuse to dropinto the lower compartment and at the same time, part of the heat of thelower compartment to he the llltl transmitted to the upper compartment,which, While not intense enough to destroy the drum 6, will serve topreheat and dry the refuse passing through the drum 6. The

. platform 12 onto the grate 14 on which it will be burned to ashes andclinkers. The combustion air for this process enters the clinker chamber15 through the holes16 be fore passing through the material on thegrate.

' As soon as one charge' is completely burned, the doors 17 will beopened and the remaining clinkers' will be removed from the gratethrough the space 18 into the clinker chamber 15. In the latter theclinkers will be cooled by the air of combustion before being dischargedthrough the valve 19 into the cars 20.

The gases of combustion leave the incinerating chamber through the flue21. The large area of the dust chamber will decrease the velocity of thegases considerably, thereby causing most of the flue dust to settle inthe dust chamber 8. From the latter the gases Will pass through the flue22 into the smoke flue 13. The excess of air in the waste gases willburn all combustible matter that passes through the perforations of thedrum 6. The fine incombustibles, however, will be sterilized by theintense heat before being discharg'edfrom the dust chamber.

It is obvious that this process of disposing of the fine constituents inthe refuse, instead of either charging it into the general incineratingchamber or burning it in a special furnace, will materially increase thecapacity of the incinerator, thereby decreasing operation expenses perton of refuse.

'This process is of still greater use, if'a brick plant is connectedwith the incinerator in order to use the broken and ground clinkers formanufacturing so called sand-lime bricks for the reason, that sand andashes remain loose in the dust chamber, while on the ate they would meltinto clinkers, whicfi would have to be ground up again.

What I claim and desire to secure by Letters Patent is:

1. A process of treating refuse, consisting in feeding the said refuseso that the fine particles will be directly charged into a zone situatedbeside the incinerating zone and the coarse particles will be directlycharged into the incinerating zone, and causing the Waste gases of thelatter to pass through said first named zone.

2. A process of treating refuse, consisting in feeding the said refuseso that it Will be separated into fine and coarse particles, causingsaid coarse constituents of the refuse to be charged directly into theincinerating zone and the fine constituents of the refuse into a zoneoutside of said incinerating zone, leading the waste gases from saidincinerating zone through the said outer zone and causing thecombustible matter of said fine particles to be burned and thenoncombustible matter thereof to be sterilized.

3. A process of treating refuse, consisting in sifting the refuse so asto separate the fine and coarse particles of the latter and to deliverthe coarse particles directly into the incinerating zone and the fineparticles into a zone outside of said incinerating zone, leading thewaste gases from said incinerating zone through said outer zone andcansing the combustible matter of said fine par ticles in said outerzone to be burned and the noncombustible matter thereof to besterilized.

4. A process of treating refuse which has been separated in fine andcoarse particles, consisting in delivering the coarse constituents ofthe said refuse directly into the incinerating zone and the fineconstituents thereof into a zone of comparatively great area and locatedoutside of said incinerating zone, leading the combustion ases from saidincinerating zone through sai outer zone so as to burn the combustiblematter of said fine particles and sterilize the non-combustible matterthereof,

In testimony whereof I affix my signature in presence of two witnesses.
